Be it'known that I, Sonomon Snvnnn, of. Herrisville, in the county of Butler, and State of Pennsylvania,

and'I do herehydeels're the following to'be s full, clear, end exact description of the same, snflicient toena ble pnnyi'ng'drewings, forming'pert of this specification, in which Fight-e1 is an end elevation,

' Theohject of this invention is-t'o simplify and render more perfect'the spool-holding and ten siomdeviees of sewing-machines,'by'which a'ny kindof ithread, whether even or uneven, and whether prepared tenths sewi g. machine or not, can'be used without-diifi6ulty. In the drawings, I 1

B represents a metallic plate, resting upon the pnr't'A, and having oneend'tnrned up, es shown (it B form;

p '0 represents 1a flat plate, hsvingflenges, c 0, turned down along its side. edges, 'nnd restirig lengthwisei upon the plaitjeFfb'ein'g snpportedflhy its'fisnges, which are riveted'tii the plate B, under-it, The'other end ofthe .spool-shett'is supported by'and bears in n stzindnrd, D, the lower end of which, e, is bentinto a. horizontal in position. I i v I I v v E is a knob, by which'the foot of "the standard can be more conveniently ins erted into or removed from its socket. p r F is the spool shaft, being ninde BqH.fl-1'9,l&l\d provided with e flat spring,'f, lying along'it, to keep the spool Ifirmly fixed in position, and G- is the spool in position on its shaft. The spool is inserted upon the shaft Hisen arm of the plste'B, extendinghorizontallyontwerd: from its side, then bending npvvard, and terspringtension bar, 'J', one endof which rests nponthe liplythe other lying upon and operst'ing like it hrake, :inlconnection-with. a. grooved pulley, K,'fixed to and revolving with the spool shsft, By clnmpin'g the be: down 'wi th difierentdegreesot' force, the friction of the her If upon'the pulley will: give any required tension toihe L is an arm, somewhat similar in shape to the arm H, but not forming e. part-of the plate Br .On the com lin'ge screw, m,' which serves the 'trip'lepurnose'of Qth'us fastening the arm L,of attaching the plste B to the any position relative to the other part's o tl thefinnchine.

The thresd-guideis in theform of 'a-short, deep'spo'ol, providedwith npin,n, projecting out fromits body,

the thread ivhichis feeding from the spool-tothe guide is kept entirely sepwsrate fron that ps rt which is feeding pin n maybe brought to hny inclinstio'ntowerds or from the spool, so that the. thresd' niay be fed froin the long'ns desiredl p I I I A p U I 7 Besides-theextrsme ch'espness, simplicity, and perfection of operation attained, in this device, it may be 'pbserved that,'whenthetension is onee'e'djust edflhe spool can he ohangedsny numher of times without dis turbing the tension, and withoutany necessity for rte-adjusting it. It is only necessary to pull the standard D out, remove the spool, and place another on the shaft, and push the standard into place again, and the apparatus is in the same condition as before, with a. new spool in place of the old one.

' The device has beenthoroughly testedoand it is found to work perfectly with :iny common sewing-thread.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- The tension-apparatus above described, when its several parts are constructed and combined to operate substantially in the manner and for the purposes set forth.
